Leasing & Hire Purchase

We offer the financing options leasing and hire purchase for selected products exclusively to entrepreneurs, businesses, and self-employed individuals, starting from a net purchase value of €1,000. Below you will find the key differences between the two forms of financing.

Leasing

Under a lease, the product is made available to the lessee for use in return for regular lease payments. The product is recognized on the lessor’s balance sheet. As a rule, lease payments can be claimed as business expenses for tax purposes. These are gross payments, and VAT is charged throughout the entire term. Once the agreed basic lease term has expired, the product can generally be purchased.

Hire purchase

In economic terms, hire purchase is equivalent to an installment purchase. The product is recognized as an asset on the hire purchaser’s balance sheet and depreciated in accordance with the official AfA depreciation tables. Upon payment of the final hire-purchase installment, ownership of the asset transfers to the hire purchaser. VAT must be paid in full with the first hire-purchase installment (a pass-through item).

Shipping & Delivery

We ship our goods either by parcel service or by freight forwarder, depending on their size, weight, and nature. We select the shipping method at our reasonable discretion.

The delivery times stated in the online shop are non-binding estimates, unless a binding delivery date has expressly been agreed in writing. They are based on the information available from our manufacturers, suppliers, and logistics partners at the time the order is placed.

A large proportion of the products offered are shipped directly from the manufacturer or from external central warehouses (direct shipping). As a result, delivery times may differ from the stated estimates. Delivery delays may occur particularly in cases of material shortages, production delays, supply bottlenecks, force majeure, or other circumstances for which we are not responsible.

Disclaimer of liability:

We accept no liability for delivery delays resulting from circumstances beyond our control. This applies in particular to delays caused by manufacturers, upstream suppliers, transport companies, or other third parties. Liability for any resulting damages, particularly indirect damages, consequential damages, or loss of profit, is excluded to the extent permitted by law.

Partial deliveries are permitted insofar as they are reasonable for the customer. They will not result in any additional shipping costs unless otherwise agreed.

The exact delivery time for an item can be provided individually on request, either before or after the order is placed.

Please contact us by telephone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.

If significant delivery delays occur, we will inform the customer without undue delay. The customer’s mandatory statutory rights remain unaffected.

RPB Safety Cool Air Tube – breathing air cooling for Nova 3 and Nova 2000

The RPB Safety Cool Air Tube is a compact cooling device for compressed-air-supplied blast helmets. It can cool the incoming breathing air by up to approximately 18 °C below ambient temperature, thereby increasing wearing comfort in hot working conditions.

The device operates according to the vortex tube principle and is integrated directly into the breathing air supply. The airflow, and therefore the cooling performance, can be adjusted using the regulator.

How it works

The Cool Air Tube uses part of the supplied compressed air for temperature separation. The cooled air is directed to the supplied-air helmet, while the warm exhaust air escapes through the device opening. Therefore, the compressed air source must be adequately sized.

📌 Important:
The device may only be operated with approved breathing air hoses, suitable breathing air quality, and within an approved RPB respiratory protection configuration.

Maintenance and care

✔ Keep the regulator and exhaust opening clear
✔ Clean the device regularly
✔ Check connections and belt for damage
✔ Check operation before each use
✔ Use only approved spare parts
